Abstract

L'invention concerne un procédé pour transmettre des données critiques en temps réel au moyen de messages de données (DT) dans un réseau de données. Ces messages de données contiennent une identification, des données utiles et un état de transfert. Selon ledit procédé, les messages de données erronés sont remplacés par des messages de remplacement possédant la même structure que les messages de données. Chaque message de remplacement possède la même identification que le message de données qu'il remplace et il est de ce fait acheminé par les noeuds de commutation par lesquels le message de données aurait été acheminé s'il n'avait pas été erroné. Ces messages de remplacement peuvent contenir des données concernant le type d'erreur de transmission.
